EXPLQSIVE MATERIAL.

To all whom it may concern:

Be it known that we, Cmusrnx J OHANNES STAUTSBOLL LUNDSGAARD and KAJ Tomas HERBST, subjects of the King of Denmark, residing at Vejen, Denmark, and Braband, Denmark, respectively, have invented new and useful Improvements in Explosive Materials; and we do herebydeclare the following to be a full, clear, and exact description of the same.

The object of the invention is'to provide an explosive which-has a high explosive power and a high degree of stability which advantageously may be used for any military or civil purpose where explosives are employed.

Another object of the invention is to provide an explosive of the kind described which which shall be substantially insensible against moistness.

A further object of the invention is to provide a detonator containing our new explosive.

With these and other objects in view the explosive consists of or comprises a erchlorate of a methyl-substituted ammonium compound.

It is a well known fact that eflicient and stable explosives can be produced by the action of perchloric acid or perchloric compounds upon cyclic ammonium compounds. It has also been tried to produce perchlorates of alifatic amino compounds, VIZ, ethylenediamine and diclyan-diamine, for explosive purposes, but so'far as we are aware these substances have not been used in large scale due to their hygroscopic character and high costs of production. It has now been found in practice that eflicient and stable explosives can be obtained by the action of perchloric acid or perchloric compounds upon methylamine, dimethyl-amfine, trimethyl-amine,

tetramethyl-ammonium or compounds con tainin one or more of said substances, where y the corresponding perchlorates are formed. Said perchlorates are rather insensible against moistness except the perchlorate of dimethyl-amine. Thus the perchlorate of methyl-amine certainly is freely soluble in water, but it is only slightly hygroscopic, while the perchlorate of tetramethyl-ammonium dissolves with diiliculty in water. Moreover these substances are Specification of Letters Patent.

very stable. Thus they may be subjected to a temperature of 150 C. for a long period and they maybe stored for several years An explosive of the kind described which has an especially high explosive power is the perchlorate of methvl-amine. Said substance may be produced, say by neutralizing dilute perchloric acid by a solution of methylamin and subsequent vaporization and crystalliza tion. It is found in practice that 0.25 g. of

the resulting perchlorate compressed inacopper cap by a pressure of 1500 kg. 'p'r. cm and ignited by a charge of 0.4 mercuric fulminate forms a hole of a dlameter ofabout 8-9 mm. in a lead plate of 7 mm.

thickness,when the cap is disposed vertically upon the surface of the lead plate. This experiment shows that the substance in question has an exceptional brisant action and efiiciency which partially is due to its rather ideal composition with respect to the proportions of the carbon, hydrogen and .ing and the like purposes) either in pure .55

state or in mixture with other substances.

Preferablythe new explosive may be used as an admixture to well known explosives, whereby the efliciency of the latter is increased. v

Moreover the new explosive may advan tageously be used as an intermediate charge in detonators, exploders or the like. Furthermore the pure explosive or mixtures of the same may be mixed with carbonates 'or' hydroxydes of sodium, calcium, magnesium or the like in order to neutralize the acid 1.
